256GB DDR4 ECC RDIMM kit

This NEMIX RAM kit delivers 256GB of registered DDR4 3200 memory in four 64GB modules. It is built for Thinkmate high-density servers that require ECC RDIMM modules with a 4Rx4 organisation. The kit runs at 1.20V with CL22 latency.

For Thinkmate HDX server upgrades

Suits administrators expanding memory in compatible Thinkmate HDX-QT24-52E3, HDX-QN24-52E3 or HDX-QT24-32E3 systems. Not for workstations or desktops that accept only unbuffered UDIMMs, nor for platforms limited to lower capacities or different ranks.

Capacity and headroom

The 256GB total supports large virtualisation clusters, in-memory databases and heavy multi-tenant workloads. Four 64GB ranks fill four slots, leaving no room for further expansion on a four-channel board without replacing modules.

Questions about this item

Does my server need 288-pin DDR4 RDIMM slots to use this 256GB kit?

Yes, each 64GB module is a 288-pin DDR4 RDIMM; the motherboard must provide four registered DIMM slots that accept DDR4 memory.

Can I mix these CL22 3200MHz modules with slower DDR4 RDIMMs already installed?

The system will run all populated channels at the speed and latency of the slowest installed module, so older DDR4 RDIMMs will lower the effective data rate.

How do I confirm the full 256GB is recognised with ECC active after installation?

Enter the BIOS or UEFI firmware on boot and verify that total memory shows 256GB and that ECC status reports as enabled or active.
